Found a solution to tapping directly into track power for the charge, an isolated step down converter.  Add a bridge rectifier and cap, and all is well.  This eliminates the issue of the perpetual motion charging.

 

Unless you're worried about the universe ending as a result, this is a solution looking for a problem. The lost energy due to charging while unpowered is around 3-5% of the energy stored in the cap. I mean, we're talking demonstrated 8 to 10 seconds runtime as it is, in a tidy two-wire package.

But if it's keeping you up at night...
